b. trigonal planar
c. linear
d. square planar
In which of the following molecular shape dz2-orbital must not be
involved in bonding?
a. pentagonal planar
b. trigonal planar
c. linear
d. square planar
Solution:
a. pentagonal planar ⟶ sp3d [s + px + py + pz + dz2 + dx2-y2 + dxy]
b. Trigonal planar ⟶ sp2 [ s + any two p]
c. Linear ⟶ sp2 [s + any one p]
⟶ sp2 [s + any two p]
⟶ sp3 [s + px + py + pz]
⟶ sp3d [s + px + py + pz + pz2]
d. square planar ⟶ sp3d2 [s + px + py + pz + dx2-y2 + dz2]
